Title: Statistical Majorana Bound State Spectroscopy
Authors: Alexander Ziesen, Alexander Altland, Reinhold Egger, and Fabian Hassler
Abstract summary: Tunnel spectroscopy data for the detection of Majorana bound states (MBS) is often criticized for its proneness to misinterpretation of genuine MBS with low-lying Andreev bound states. Here, we suggest a protocol removing this ambiguity by extending single shot measurements to sequences performed at varying system parameters.

Abstract: Tunnel spectroscopy data for the detection of Majorana bound states (MBS) is often criticized for its proneness to misinterpretation of genuine MBS with low-lying Andreev bound states. Here, we suggest a protocol removing this ambiguity by extending single shot measurements to sequences performed at varying system parameters. We demonstrate how such sampling, which we argue requires only moderate effort for current experimental platforms, resolves the statistics of Andreev side lobes, thus providing compelling evidence for the presence or absence of a Majorana center peak.

Certification of two-qubit quantum systems with temporal inequality [0.0]
Self-testing of quantum devices based on observed measurement statistics is a method to certify quantum systems using minimal resources. We propose a self-testing protocol to certify the above two-qubit states and measurements without the assumption of compatibility conditions. Our protocol is based on the observation of sequential correlations leading to the maximal violation of a temporal inequality derived from non-contextuality inequality.

Reconstructing Graph Diffusion History from a Single Snapshot [87.20550495678907]
We propose a novel barycenter formulation for reconstructing Diffusion history from A single SnapsHot (DASH) We prove that estimation error of diffusion parameters is unavoidable due to NP-hardness of diffusion parameter estimation. We also develop an effective solver named DIffusion hiTting Times with Optimal proposal (DITTO)

Robust High-dimensional Tuning Free Multiple Testing [0.49416305961918056]
This paper revisits the celebrated Hodges-Lehmann (HL) estimator for estimating location parameters in both the one- and two-sample problems. We develop Berry-Esseen inequality and Cram'er type moderate deviation for the HL estimator based on newly developed non-asymptotic Bahadur representation. It is convincingly shown that the resulting tuning-free and moment-free methods control false discovery proportion at a prescribed level.

Targeted Separation and Convergence with Kernel Discrepancies [61.973643031360254]
kernel-based discrepancy measures are required to (i) separate a target P from other probability measures or (ii) control weak convergence to P. In this article we derive new sufficient and necessary conditions to ensure (i) and (ii) For MMDs on separable metric spaces, we characterize those kernels that separate Bochner embeddable measures and introduce simple conditions for separating all measures with unbounded kernels.

Statistically significant tests of multiparticle quantum correlations based on randomized measurements [0.0]
We introduce hierarchies of multi-qubit criteria, satisfied by states which are separable with respect to partitions of different size. We analyze in detail the statistical error of the estimation in experiments and present several approaches for estimating the statistical significance.

Nonlocality, steering and quantum state tomography in a single experiment [1.8631700158180744]
We investigate whether paradigmatic measurements for quantum state tomography can be employed to certify quantum correlations. This allows us to perform state tomography on entangled qutrits, a test of Einstein-Podolsky-Rosen steering and a Bell inequality test, all within a single experiment.

Unitary Symmetry-Protected Non-Abelian Statistics of Majorana Modes [2.0502751783060003]
We show that braiding two vortices with each hosting $N$ unitary symmetry-protected MZMs generically reduces to $N$ independent sectors. This renders the unitary symmetry-protected non-Abelian statistics. Our work opens a new route for Majorana-based topological quantum computation.
